Spin-On Filters

Integrated filtration solution for oil, fuel and hydraulic systems | Fast installation, reliable performance and easy replacement

PowerSep Spin-On Oil Filter
PowerSep Spin-On Fuel Filter

Product Overview

Spin-On filters are among the most widely used and reliable filtration solutions in the automotive, construction, agricultural and industrial equipment sectors. With their integrated design — cartridge and metal canister in one assembly — they allow fast, safe installation and can be replaced without opening a separate housing. Compact construction, reliable sealing and consistent performance have made Spin-On filters the standard choice across lubrication, fuel and hydraulic systems.

Design and Construction Features

Robust Metal Canister

Steel canister withstanding high working pressures with resistance to impact and corrosion

Advanced Filter Media

Multi-layer cellulose or synthetic fibre media with high efficiency for fine particle capture

Calibrated Bypass Valve

Ensures oil/fluid flow under filter clogging conditions or cold start

Anti-Drain Back Valve

Prevents fluid drain-back after engine shutdown, avoiding dry start conditions

Precision Sealing

Heat and chemical resistant O-ring to prevent leakage under demanding conditions

Consistent Quality Control

Pressure, leak and separation efficiency testing on every production batch

Applications

Spin-On filters are used across a wide range of systems:

Engine Oil

Lubrication filters — protecting bearings and moving parts against wear

Fuel

Fuel filters — removing suspended particles and water from petrol or diesel

Hydraulic

Hydraulic filters — extending the life of pumps and valves in pressurised circuits

Industrial Systems & Diesel Generators

Ensuring reliable performance under heavy-duty operating conditions
